Terramok

Terramok is an ancient titan vault, created to hold Theradras, former princess of the vile earth elementals and legendary mother of the centaur race. It is hidden behind a series of spiked barriers in the center of a mesa, located in Maraudon in Desolace.[1] Terramok appears to be part of inner Maraudon. There are in-game references to the subzone, namely just as "Terramok" or "the crystal caverns of Terramok"[2].
